Writes Brian Kaylor, this is the second such meeting convened by Robison, who calls Perry his "prayer partner," following a September confab at the Grand Hyatt DFW Hotel. But there is precedent:

In 1979, Robison led a similar secret meeting in Dallas to plot how to defeat then-President Jimmy Carter. That effort culminated in an August 1980 rally with Republican presidential hopeful Ronald Reagan that helped Reagan mobilize pastors for his presidential campaign.

Following up on his September 2010 meeting, Robison held two conference calls in March with 35 conservative Christian leaders.

"As we discussed how to find common ground to address the serious challenges facing our nation, some asked that we seek God for very specific, meaningful direction," Robison wrote on his blog about the calls. "They wanted to know how to help focus the prayers of believers on specific issues, make wise suggestions and take positive action."
